Identification of gunshot residue: a critical review
Forensic Science International, 2001A review of the scientific papers published on inorganic gunshot residue (GSR) analysis permits to study how the particle analysis has shown its capability in detection and identification of gunshot residue. The scanning electron microscope can be the most powerful tool for forensic scientists to determine the proximity to a discharging firearm and/or ...

Preliminary evaluation of the persistence of organic gunshot residue
Forensic Science International, 2012The organic components of gunshot residue (OGSR, also called firearms discharge residue (FDR) or cartridge discharge residue (CDR)) have been studied and discussed in the literature. These residues, consisting of particulates such as burned and unburned powder as well as molecular compounds, are rarely used in casework except for purposes such as ...

Journal of Radioanalytical Chemistry, 1973
The deposits resulting from the discharge of 0.22 calibre ammunition have been studied by neutron activation analysis and autoradiography. Material ejected forward with the bullet, and material ejected between a revolver cylinder and barrel, have been collected, both on filter paper an on a variety of clothing fabrics.

Examination of Gunshot Residues
Journal of Forensic Sciences, 1974Abstract The examination of gunshot residues in a forensic science laboratory should be a series of integrated procedures. The Southwestern Institute of Forensic Sciences includes both the Office of the Medical Examiner and the Criminal Investigation Laboratory.

Pyrotechnic Residues in Gunshot Residue Analysis
Proceedings, annual meeting, Electron Microscopy Society of America, 1985Particle analysis by scanning electron microscopy with energy-dispersive x- ray analysis is one of the current methods used in crime laboratories to aid law enforcement in identifying individuals who have recently fired or handled a firearm. During the discharge of a firearm, the high pressure caused by the detonation of the cartridge materials forces ...

Close Proximity Gunshot Residues
Journal of Forensic Sciences, 1986Abstract Intuitively, a hand held in close proximity to a firearm at the instant of discharge will intercept a significant amount of gunshot residue, even though the hand did not actually come into contact with the weapon. There is, however, little information specifically described in the forensic science literature concerning the ...

Journal of Forensic Sciences, 1982
Abstract Scanning electron microscopy combined with energy dispersive X-ray analysis (SEM-EDX) was used to determine new structural criteria to further substantiate the view that gunshot residue (GSR) particles have a characteristic structure. Because GSR particles are formed by rapid cooling from extreme temperatures and high pressures,

Gunshot Residue, Ten Years Later
The American Journal of Forensic Medicine and Pathology, 1991Gunshot residues may be central to a competent reconstruction of a shooting incident. When a young boy was shot in the neck by a playmate using a .22-caliber single-action revolver, permanent paralysis from mid-thorax downward ensued. Ten years later the victim sued the importer, the vendor, the German manufacturer, and the shooter's family ...

Detection of gunshot residues in routine CTs
International Journal of Legal Medicine, 2000The forensic assessment of non-fatal gunshot wounds often proves to be difficult as wounds have usually been cleaned and protected with a sterile bandage by the time of the examination. The aim of our investigation was to test the possible application of computed tomography (CT) for the forensic assessment. Doing so raised the questions whether gunshot

Voltammetric analysis of luminescent markers in gunshot residues
Journal of Forensic Sciences, 2023AbstractCurrently, SEM‐EDS is used to detect gunshot residue (GSR) from the presence of Ba, Pb, and Sb in the sample. However, the development of new nontoxic ammunition (NTA) has prevented conventional metals from being found. In this work, we aim to determine the presence of an inorganic luminescent chemical marker based on rare earth in gunshot ...
